Correlation transfer in large-spin chains

TL;DR

This paper demonstrates that in large-spin one-dimensional chains, transient spin-spin correlations can be amplified through correlation transfer from internal to external degrees of freedom, modeled effectively with a semiclassical phase-space approach.

Contribution

It introduces a semiclassical phase-space method to describe correlation transfer in large-spin chains, revealing how correlations can be enhanced from initial factorized and squeezed states.

Findings

Transient correlations can be significantly enhanced in large-spin chains.

Correlation transfer from internal to external degrees of freedom is effectively modeled semiclassically.

The approach provides insights into controlling correlations in quantum spin systems.

Abstract

It is shown that transient spin-spin correlations in one-dimensional spin S>>1 chain can be enhanced for initially factorized and individually squeezed spin states. Such correlation transfer form "internal" to "external" degrees of freedom can be well described by using a semiclassical phase-space approach.
